Good Saturday morning. Axios.com will have all-day coverage from our reporters and videographers at #MarchForOurLives in D.C., and we'll bring you a taste of the 831 other marches planned around the world (including 50 states, 387 congressional districts).

Situational awareness: "Trump released an order [last] night banning most transgender troops from serving in the military except under 'limited circumstances," following up on his calls last year to ban transgender individuals from serving." (AP)

On #MeToo: "I hope in the future for some form of reconciliation. Because I think all men are guilty. ... Are we really going to have only capital punishment? Because right now, that’s what we have."

1 big thing: Trump's new era of high risk

On Jan. 26, just over a year into his presidency, President Trump had a president's dream: peace and prosperity. The Dow Jones industrial average, S&P 500 and Nasdaq all hitrecord highs.

Since then, Trump has injected multiple new risks into the system.

Yesterday, "U.S. stocks suffered their worst week in more than two years, signaling mounting investor anxiety over whether factors from restrictive trade policies to rising interest rates could disrupt the nine-year bull market." (WSJ)

N.Y. Times: "Aides said there was no grand strategy to the president’s actions, and that he got up each morning this week not knowing what he would do. "

So what's happened in the past two months?

Checks inside the White House are gone, and Chief of Staff John Kelly's controls have been circumvented.

Critics of China and trade have been empowered.

Hawks have been installed at NSC and State.

Trump is stirring for a Mueller fight.

The conversation:

CFR President Richard Haasstweets: "This is the most perilous moment in modern American history-and it has been largely brought about by ourselves, not by events."

Jeremy Bash, former CIA and Pentagon chief of staff, on "Morning Joe": "I think the president is assembling a War Cabinet. To take a war to Bob Mueller, he's got Joe diGenova. To take a trade war to China, he's got Larry Kudlow. And now, to actually have a real war, he's got John Bolton. And the only question is: Will we find ourselves in a military conflict vis-à-vis North Korea or Iran or both?"

N.Y. Times Quote of the Day ... Tong Zhao, a nuclear policy expert at the Carnegie-Tsinghua Center for Global Policy in Beijing, on the apprehension of American allies in Asia about the appointment of John Bolton as national security adviser: “People are trying to avoid appearing terrified, but people are deeply concerned.”

The Trump view ... A source close to the president told me:

"I personally reject the premise that there is inherent 'risk' in Trump being more Trump."

"He's got 15 months under his belt, and is feeling more comfortable and confident in the job."

"The economy is booming ... ISIS is obliterated. He's got China to the table to help with NoKo in unprecedented ways."

2. A first: Trump base incensed at Trump

A former White House official tells me that online conservative ire (Laura Ingraham, Ann Coulter, Mark Levin, etc.). about the spending bill President Trump signed yesterday — after a puzzling tweeted veto feint — "is the hardest I've seen ever seen the base turn on Trump over anything."

The official continued: "A big reason why people voted for him was because of his apparent willingness to stand up to the entrenched political class in both parties. Voters wanted a fighter who wouldn't back down to 'the swamp' like a 'typical politician.'"

"They were attracted to his strength and alpha mentality, but unfortunately yesterday's fake veto threat did little but make him look weak ... and his base took notice."

"Trump's base is literally begging him to throw McConnell/Ryan under the bus after today. Just search 'McConnell Trump' on Tweetdeck and you will see what I mean."

A White House official replies that a six-month continuing resolution would have led to no better outcome:

"The veto advocates hate Ryan and McConnell. Not good enough reason for us to veto."

"Thought one of the reasons DJT was elected was to get things done in a broken D.C.?"

Touché: "If there was a shutdown, would Axios headline praise Trump as shrewd negotiator, or ridicule as dealmaker who can't make a deal to fund the government?"

3. Stat du jour

Stunning six-figure stat on school shootings ... "Collateral damage of this uniquely American crisis," per WashPost A1:

"Beginning with Columbine in 1999, more than 187,000 students attending at least 193 primary or secondary schools have experienced a shooting on campus during school hours, according to a year-long Washington Post analysis."

"This means that the number of children who have been shaken by gunfire in the places they go to learn exceeds the population of Eugene, Ore., or Fort Lauderdale, Fla."

"With more than two billion users, Facebook is the top target for privacy concerns, and it is almost certain that the company will not walk away unscathed," per the Barron's cover story:

"Pressure by lawmakers and regulators in the U.S. and Europe, unease among advertisers, and anger among its users means that the company’s galloping unfettered ride on the back of user content and data is over."

"For investors, the question is whether the company can adapt without undermining the advertising model that has powered years of extraordinary growth. There is considerable doubt at the moment."

5. Andrew McCabe: Inside the nightmare

"Despite all the preparation for the worst-case scenario, I still felt disoriented and sick to my stomach."

"[A]fter two decades of public service, I found out that I had been fired in the most disembodied, impersonal way — third-hand, based on a news account."

"Shortly after getting word, I noticed an email from a Justice Department official in my work account, telling me that I had been 'removed from the Federal Bureau of Investigation and the civil service.'"
